Configuring DKIM for your Email Domain

Estimated reading: 2 minutes 317 views

DKIM (DomainKeys Identified Mail) is an email authentication protocol that confirms an email genuinely came from the domain it claims to be from. Configuring DKIM for your email domain in Zoho Social reduces the risk of spoofing and helps your notification emails reach the inbox rather than spam.

This process can only be performed by the Zoho Social portal admin.

1. Access portal settings

  1. Go to Settings > General Settings.
  2. Click Portal Settings and switch to Email Authentication.

2. Add your custom domain

  1. Click Add a domain.
  2. Enter your domain name and click Add.

The domain must match the one used in your portal admin’s email address (for example, admin@yourcompany.com).

3. Get the DKIM record

A pop-up shows the values you need: a host name (for example, _domainkey) and a TXT record value (a long DKIM public key). Click Copy next to both fields.

4. Add the DKIM record to your domain host

Add a new TXT record in your domain’s DNS settings using the host name and value Zoho provided. The exact screens vary by host, but the steps are similar, for example:

  • Hostinger: go to Domain Portfolio, manage your domain, open DNS/Nameservers, and add a TXT record with the DKIM host name and value.
  • GoDaddy: open Manage DNS for your domain and add a TXT record with the DKIM host name and value.
  • Bluehost: go to Domains, then Advanced Tools, manage your domain, and add a TXT record with the DKIM host name and value.

Keep the TTL at its default unless you have a reason to change it.

5. Verify your domain in Zoho Social

  1. Once the TXT record is added and DNS changes have propagated, which can take up to 24 hours, return to Zoho Social.
  2. Click Verify on the pop-up.

Once verified, your domain appears in the domain list along with its DKIM status.
